Mattermost is an excellent tool for team collaboration as it is an opensource and self-hosted, so you are in control of your data.

It offers similar UI and controls as slack, so this would be the easiest application you can switch to. In the free version, you can easily use it with 100 peoples.

Discord

Mostly known as the chat and voice conference for games, this app is great for gamers as it’s free, secure, and multi-platform.

The slack has a more enterprise approach whereas the basic feature of both apps (slack and discord) is the same, that is ‘team chat’.

Basic file sharing and team conversations can be done easily in discord.

There is no fee; no limits on users and control over the channels is very good.

It has no integration with others like Zapier or anything else but honestly, most of the companies don’t use it.

#6 Fleep: Group chat like slack and Task manager like Trello

Fleep’s idea for team collaboration was a mix of slack and Trello, task management and team chat combined with file sharing.

There are many integrations to choose from but this is not completely free as it limits a lot of its features in the basic free version. So, it may not be suitable for enterprise or big business.

In the basic plan, you get unlimited message history, up to 3 group conversations, and 10GB of file storage.

This is noticeably faster and cheaper as well in comparison to other slack alternatives.
